Inventor: KOYAMA JUN
IPC: G09G3/32
Filed: 2001-08-18
Abstract: PURPOSE: A liquid crystal display(LCD) device is provided to display an image by inputting n bit digital signals to have n memory circuits in each pixel, wherein the n is a natural number. CONSTITUTION: An LCD device includes a shift register circuit, a first latch circuit, a second latch circuit, a bit signal selection switch and a plurality of pixels. Each of pixels for use with a 3 bit digital degradation signal include a liquid crystal(LC) element, a capacitor(Cs) and n number of memory circuits(105,106,107). The n memory circuits(105,106,107) store n bit digital signals for converting the n bit digital signals into corresponding analog signals by the D/A converter(111) provided in each pixel so that the analog signals are inputted to the LC element. Therefore, when a still image is to be displayed, the stored digital signals are repeatedly used once the digital signals are written in the memory circuits(105,106,107). During the still image is displayed, a source signal line driving circuit and other circuits is capable of stopping their driving. Thus, it is possible that the power consumption of the LCD device is reduced.
